Book excerpt: A VINTAGE MURDER MYSTERY Rediscover Gladys Mitchell – one of the 'Big Three' female crime fiction writers alongside Agatha Christie and Dorothy L. Sayers. Christmas in the Cotswolds brings with it the apparition of a country parson, a series of poison pen letters, and a woman’s body frozen in the snow. The eminent psychoanalyst and superior sleuth Mrs Bradley has a theory about who’s behind all three and sets about a plan to ensnare the unseasonal villain. Opinionated, unconventional, unafraid... If you like Poirot and Miss Marple, you’ll love Mrs Bradley.
